## About

Pick a number from any range, roll one or many dice, or shuffle a list of items. Every draw uses your browser’s cryptographically secure random number generator so the results are not predictable and not biased.

Useful for giveaways, classroom picks, board-game decisions, dividing chores fairly, or anything else that needs an unbiased random choice. Set a min and max, choose how many numbers to draw, and copy the result.

## How to use

1. **Choose a range** — Set the minimum and maximum (inclusive).
2. **Pick how many** — One number or a batch — useful for giveaways and raffles.
3. **Or use a preset** — Roll one or many six-sided dice, or shuffle any list of items.

## Examples

### Pick a winner

Generate one number from 1 to 100 for a giveaway.

Output:

```
42
```

### Roll 3d6

Roll three six-sided dice and add them up.

Output:

```
5 + 2 + 6 = 13
```

## FAQ

### How random is this?

Numbers come from crypto.getRandomValues, a cryptographically secure RNG provided by your browser. The same API is used for TLS, password generation, and other security-sensitive work.

### Can I exclude some numbers?

Not directly, but you can reroll the draw until you get a value that works for you. Each draw is independent.

### Is the random number cryptographically secure?

Yes. The tool uses the browser's crypto.getRandomValues(), which is the platform's secure random source. The output is suitable for cryptographic keys, salts, nonces, and any place where predictability is a problem.
